GEORGE VAN WAGENEN, OF NEYV YORK, N. Y.

FASTENING FOR DOORS.

SPECIFICATION forming part of Letters Patent No. 372,830, dated November 8, 1887.

Application filed February 28, 1887. Serial No. 229.249. (No model.)

Be itknown that I, GEORGE VAN WAGENEN, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Fastenings for Doors, of which the following is a specification.

My invention is applicable to doors which open either by sliding or by swinging upon .hinges, and is more particularly intended for the doors of car-heating stoves and stoves employed for heating vessels, where the stove is subjected to shock or jarring action, and where accidents are liable, which, in case of the doors opening and releasing the hot coals, will frequently set fire to the car or vessel.

In my application for Letters Patent, Serial No. 228,692, filed February 24,1887, I have shown and described a door-fastening which consists of a pivoted latch secured to the door and engaging a shoulder or projection on a keeper which is secured to the casing, and I have there shown a bolt sliding above the latch into and out of the keeper, in order to hold the latch down and prevent its being raised sufficient to disengage it from the keeper. I have also in that application shown a pendulum-lever or weighted tumbler, which may be turned by a knob or handle, and which comprises an arm whereby the sliding bolt is operated, a cam for lifting the latch, and a weight wherebythe lever is caused to gravitate to a position which insui es the sliding of the bolt into the keeper above the latch.

The object of my present invention is to provide, in connection with the pivoted latch, which engages a shoulder or projection on the keeper,'means upon the casing adjacent to the keeper, whereby the latch will be held down in case the sliding bolt, which moves above it, is caused by gravity to slide out of the keeper when the stove is overturned or thrown into an abnormal position.

In carrying out my invention I combine with the door and its casing a keeper on'the casing and a pivoted latch on the door, adapted to engage a shoulder or projection on the keeper, 2. locking-bolt, and a weighted and pivoted tumbler on the casing, the tumbler being connected with the bolt, so as to produce the sliding movement of the bolt into the keeper above the latch to prevent the raising of the latter.

The invention will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of portions of a door and its casing to which myimproved fastening is applied, the capplates covering parts of the fastening being removed; and Fig. 2 is a view similar to Fig. 1, but showing the parts in an inclined or abnormal position, such as would be produced by the tilting of the stove at a sharp angle.

Similar letters of reference designate corresponding parts in both figures.

A designates a part of the casing, and B designates a part of the door which closes upon the casing, and which may either slide horizontally or swing upon hinges, as is described in my aforesaid application.

B designates a casing or frame in which the parts of the latch are inclosed, a coveringplate which is applied to this casing or frame being removed.

G designates alatch which is pivoted at c to the frame or casing B or to the door on which said casing or frame is placed, and which'has a shoulder or beak, 0, adapted to engage a projection or shoulder, 0 upon the keeper D attached to the casingA. As here represented, this keeper forms part of a casing or frame, D, which contains other parts to which my invention relates.

E designates a bolt sliding upon the top of the latch Oand in a suitable guide, 6, and whichis adapted to enter the keeper D above the latch C. When this bolt E is slid into the keeper D above the latch, as is shown in Fig.

1, the latch cannot be raised sufficiently to disengage the shoulders 0 c and the door is held securely closed. For operating the bolt E and the latch G, I have represented a pendulum-lever or weighted tumbler, which may be operated by a knob or handle secured upon its spindle F, as is illustrated in my aforesaid application. This pendulum-lever or weighted tumbler comprises a cam, f, which is adapted when turned to bear upon and raise the latch 0, an arm, f, having 'a' pin-and-slot connection, f ,with the sliding bolt E, and a weight, f which, when the parts are at rest, tends to assume by gravity the position shown in Fig. 1, and so holds the bolt E inthe keeper D above the latch O. The movement of this pendulum-lever or weighted tumbler may be limited by stop pins f, and, by a turning movement of the lever or tumbler in the direction indicated by the arrow in Fig. 1, it acts through its armf to retract or move the bolt E out of the keeper D, then through its camf to lift thelatch G, and by pressure upon the knob or handle the door maybe moved in the direction of the arrows 8 (shown in Fig. l) to open it.

111 order to still further guard against the accidental disengagement of the latch G from the keeper D and consequent opening of the door in whatever position the parts may as sume, I have arranged in the casing or frame I) a SIlIJPiQIHOIltEL] sliding bolt, E, which is fitted to suitable guides, e, and which is controlled by a weighted tumbler, E fulcrumed or pivoted at 6 and the swinging movement of which is limited by stop-pins e.

In the normal position of parts, when the stove is upright, the supplemental bolt E has no function whatever and remains idly in the position shown in Fig. 1; but in case the stove or otherstructure be so tilted or changed in position that the parts assume the position shown in Fig. 2, or any analogous thereto, where the weighty" will tend to move the bolt E out of the keeper D, the weighted tumbler E will, by the force of gravity, move the supplemental bolt E into the keeper D above the latch C, thereby blocking the latch and preventing its being raised out ofengagement with the keeper, even though the main bolt E be wholly with drawn from the keeper. Gravity will always tend to move the weighted tumbler Eand the weightf in the same directiomand as the bolts E E must I110? in opposite directions in order to come into operative position and block the latch C, it follows that any position whatever of the stove or other structure which will pro duce the withdrawal of the bolt E from the keeper D will insure the certain entrance of the supplemental bolt E into the keeper D, still blocking the latch and preventing its being raised out of engagement with the shoulder 0 on the keeper. The parts should be all fitted so as to insure their free movement and so that no rust or other condition will prevent them from certain operation.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a door and its casing, of a keeper on the casing, a pivoted latch on the door adapted to engage a shoulder or projection on the keeper, and a locking-bolt and weighted and pivoted tumbler on the cas ing, the tumbler being connected with the bolt, whereby, when the tumbler is swung on its pivot by gravity, it will produce a sliding movement of the bolt to enter the keeper above the latch and prevent the raising of the latch, substantially as herein described.

2. The combination, with a door and its casing, of a keeperon the casing having a projection or shoulder, a pivoted latch on the door for engagement with said keeper, a bolt sliding above the latch into and out of engagement with the keeper, and a pendulum-lever or weighted and pivoted tumbler for actuating said bolt. and a supplemental bolt and pivoted and weighted tumbler upon the casing, the said weighted or pivoted tumblers being connected with the bolts so as to produce the sliding movement of one or the other of the bolts into the keeper above the latch when the stove is overturned, substantially as herein described.
